:My invention relates to shoe skates andv has for itsv basic object to provide a combina tion shoe and skate in which `the skate 'is .quickly detachable and vattachable and in 5 which the shoe isadaptedy to be used for walking purposes. To be more explicit, it is my purpose to provid-can arrangement wherein the skater ,canfput on his skating shoes and Walk to a skating rink with-'the same com-y 10 fort' and the same protection from the weather yas is found in ian ordinaryA pair of shoes and When'he arrivesat'therink can quickly ate tach his skates .to/tlie'shoes and then be ,pro-

vided with a pair ofshoe skates in which the i5 skates are as rigidlyattached as though they were permanently screwed or riveted to the shoes. f' l I Anobj ect'of my inventionis carried outin a" v vifac-e'lwith no= projections or'` perforationsV which would catch against or .be hooked by s any rough or protruding portions' of a surface being walked upon.

A further object isto providea half soleY lwhich constitutes thewearing surface for the shoe and also cooperates with the full sole in providing an eXtra thickness of sole torinsulate against heat,'to aid in the exclusion of moisture and to wearing.`

A further object is to provide a pocket arrangementhaving the `requisite strength for N rigidily 'securing'a' skate tol the shoeland yet adapted to allow instant removal of the skate y without diliiculty'.

Another object is to provide'novell means for attachment of the skate to the heel of the shoe in order to obtain rigidity, strength and 59 quick atachabiiay and detaeiabiiity. The

functions of the heel attaching means are,`

to attach the skate to the heelY of the shoe,y as above noted, and, secondly, to securethe skate againstv longitudinal movement relative to rtheshoe, lateral pressure being carried. at the forward "eXtremity,by Vvthe sole` pocket, and at the rear extremity, by the heel. attaching means.y v. i Y

l 'i he haif sole 13 is secured to the vamp 1Q or to the outer edge of the full sole 11lby a lin-c of stitching let extending around the sides of the half sole and across the toe. Y

he rear edge of the half sole is thus left unsecured to the full sole, forming a rearwar'dly facing opening. rlhe rear edge of the half sole is preferablywbevelled as at 15,

merging the surface of the half sole with that.

of th'e'full sole. f y

it will now be seen that the half'sole and full 'sole form betweenthem a rearwardly opening. pocket having substantially the shapev of thetread portion of an ordinary shoe, .which shape may vary to fit the needs of various feet, as in ordinary shoe constructions. in inost.c'as`es,'the tread. portion of a shoe decreases .in width toward the toe and the pocket will thus in most cases be somewhat triangular in shape-or decreasing in width ytoward its forward extremity. There is some advantage in having the'pocket thus wedge-shaped or decreasing .inl width toward itsforward extremity. Atighter'fit can be secured between the pocket ,and the tongueof the skate, (which will later be more fully described in detail) where .both tongue and pocket are made to converge somewhat toward their forward extremities. By forcing such a tongue forwardly, its engagement with the pocket may be tightened.V However, it is not entirely essential that this pering` or converging Vconstruction be employed. rfhe pocket might be formed with parallel sides, irrespective of the shape v,of the sole ofthe shoe by bringing the lines of stitching rearwardly in parallel relation rather than following the con-tour of the sole. v[i careful Fitting of the tongue of the skate into such a parallel sided pocket would still give a snug tit and sufficient lateral support to prevent wobblingof the skate relative to the shoe. r1`he converging construction, however, has a tendency to tighten and rigidify the connection. c Y Y The halfl sole maybe made of leather or composition," although preferably of good sole leather to give the desired strength of siipportto the skate. It. is to be noted at this point that the'half so-le has a, smooth continjioussurfa'ce adapted togive the same walking coinfortnas is found inwordinary shoes, to save the full splefrom wearing and thus to preserve the life of the shoe and to help in the exclusion of moisture and heat or cold. It will be understood that the half sole does not fully protect against moisture vobtaining access to the full sole because of the pocket opening but it will do so to some extent where the shoes are used in walking on a moist surface, as compared with actually wading through water. p surface protects against catching the shoes on cinders or other projections in the ground, thus being a very decided improvement over those types of combination shoe and skate wherein aV pocket or opening is formed in the center o-f the sole to receive the skate tongue.

Thus the rearwardly opening pocketl is a decided improvement in view of the'smooth continuous surface `ofthe half sole..

Theheel of the shoe is preferably formed of steel'or somesubstance having comparable wearing qualities and hardness in order to form a socket for the receptionv of the heel portion shown as formed of a solid block 1G of steel or The smooth lower n of the skate.y The heel issherein the like, provided with `a central socket opening hai/iner the inclinedrsides 17. It will be understood that the same effect could be obtained by forming the heel o f leather or composition and the like and inserting a socket shell of steel or the like to form the socket vi/allav The heel may be secured to the heel' portion of the sole 11 in any manner such asby means of the screws 18.V

TheA skate comprises the usual runner 19,

provided with the upwardly projecting `central post 2O andthe upwardly projecting forwardpost 21;. The central post 2O is for the purpose of supportingthe forwardly projecting tongue 22, Awhichy is preferably made with such'a sha'peas to fit-therpocket of the sole. It is not essential, howeifen ,that thetongueQQl be the'full vwidthof the pocket during the en tire length ofthe tongue. A tight fit could be obtained byforming the tongue-to completely vfill the pocket from side to side during aportion of thelength ofthe pocket, yThus the tongue would give lateral support by engagement with. the sides of the pocket during at least a portion of its length. y i Forward and rear support is obtained by a rigid heel connection, adapted to prevent movement ofthe skatelongitudinally relative to the sho-e. Thus both longitudinal and lat eral vsupport are provided.

rlhe post 21 is for the purpose of providing a Asupporting engagement between the forward extremity of the skate and the shoe. It 1willrbe understood that with the posts 20 and 21 and the tongue 22, sufficient support between the shoe and skate canbe secured for ,ordinaryskating purposes. `Howemanit adds to the support between the skate and the shoe land adds to the strength ofthe skate proper to connect theposts 2O and 21 with a forward skate portion 23, shaped to fit the contour of lUU llo

the lower face ofthe half sole I3/and thusV arranged in parallel and spaced;relation-to theftongue 22. The heel portion of the skate includesan upwardly projecting` post 2li, to

p which is secured or ywith whichis formed nter-V f grally a socket plug 25. The plug 25 is formed with inclined side faces 26 to engagey the side faces 17 of the heel'socket. l*

The plug is shaped to'fit snugly within the socket and adapted to snugly lengage the socketwhile'its upper extremity isV still spaced somewhat from the sole 11. Thus a wedging action between the plug 'and socketisfat alll times assured, even after some wear y:has

taken place.'

taper is suchthat upon forwardmovement ofthe'key into the openings, the plug 25 will be'drawn upwardly. It is, of course, preferably to taper' all of the openings 27 and 28v and to taper the key during substantially, its entire length so as to obtain its f greatest drawing action.

The key isiprovided with a threaded p`ortion 30 and onel of the openings 2'7 or 28 is provided with a: coacting" threaded portionV 31 to receive the threads 30. rlhe .key has a head"32 for engagement bythe fingers of the operator.v u f lIt will now be seen that by inserting the key through the registering openings 27 and 28 and rotating it'that it will be drawn .forwardly and will draw the plug 25` upwardly to snug engagement with the socket. Furthermore, the parts may be arranged sothat as th-e plug is drawn upwardlyutheI rear inclined faces of plug and socket will force the skate forwardly and urge'the tongue 22 into snug engagement with the' pocket. i'

rlhe operation `of attaching or detaching the skate is fairly obvious from the foregoing description but may b e summed upbriefly yat thisv point as follows :k

In attaching the skate, it is only necessary to slip the ,tongue 22 forwardly into the pocket ofthe sole until the plug 25 is in position where it canv be inserted into the heel socket. The skater may then place the skate upon the Hoor and force his heel downwardly, forcing the plug to move into the socket and thereby wedging the tongue 22 forwardly,

dueto the inclination of the rear faces of the Y 'plug and socket. The plug may be brought to the proper position toregister the openings 28 and 27 by stamping the skate against the floor or ground and the key 32 may then be inserted and used to lcomplete the wedging operation and to tie the parts together securely. A snug engagement of the tongue 22 with the sole pocket gives a firm support for the forward portion of the skate and the snug engagement' of the plugin the izheel socket gives a firm, securing. support for the'rear f portion Vof the skate: I
